A P0453 code on a Ford F150 indicates a problem with the Evaporative Emission Control System Pressure Sensor, also known as the Fuel Tank Pressure Sensor.
This sensor measures the pressure in the fuel tank, which is part of the vehicle’s evaporative emission control (EVAP) system.
P0453 code on a Ford F150
The EVAP system is designed to prevent fuel vapors from escaping into the atmosphere by capturing and storing them in a charcoal canister.
The P0453 code specifically means that there’s a high input signal from the fuel tank pressure sensor, which could indicate a problem with the sensor itself or the wiring/connectors associated with it.
Here are some steps you can take to troubleshoot and potentially fix the issue:
- Inspect the fuel cap: Make sure the fuel cap is properly tightened and not damaged. A loose or damaged fuel cap can cause pressure issues in the fuel tank.
- Check the fuel tank pressure sensor: Locate the fuel tank pressure sensor, which is usually mounted on top of the fuel tank or near the fuel pump module. Inspect the sensor for any visible damage, corrosion, or loose connections.
- Inspect the wiring and connectors: Check the wiring and connectors leading to the fuel tank pressure sensor for any signs of damage, corrosion, or frayed wires.
- Test the fuel tank pressure sensor: Using a multimeter, test the resistance and voltage of the sensor to determine if it’s within the manufacturer’s specifications. If the sensor is faulty, replace it.
- Scan the EVAP system: If the issue persists, use an advanced scan tool to perform a full EVAP system test, which could help identify any other issues, such as a malfunctioning purge valve or vent valve.
If you’re not comfortable with troubleshooting or repairing the issue yourself, it’s a good idea to consult a professional mechanic. They can diagnose and fix the problem more accurately and efficiently.

P0453 code on a Ford F150 description
A P0453 code on a Ford F150 is related to the vehicle’s Evaporative Emission Control (EVAP) System. Specifically, it indicates a problem with the Fuel Tank Pressure Sensor or the Evaporative Emission Control System Pressure Sensor.
This sensor measures the pressure inside the fuel tank, which is crucial for the proper functioning of the EVAP system. The EVAP system is designed to prevent fuel vapors from escaping into the atmosphere by capturing and storing them in a charcoal canister.
The P0453 code signifies that there is a high input signal coming from the fuel tank pressure sensor. This can be caused by a malfunctioning sensor, damaged wiring or connectors, or issues with other components in the EVAP system.
The presence of this code will typically trigger the Check Engine Light (CEL) and may result in reduced fuel efficiency, fuel odor near the vehicle, and difficulty passing emissions tests.
How much does it cost to diagnose and fix the P0453 code on a Ford F150?
The cost to diagnose and fix the P0453 code on a Ford F150 can vary depending on the specific cause of the problem, labor rates in your area, and whether you choose to have the work done at a dealership, independent repair shop, or do it yourself. Here is a general breakdown of the costs:
